MMC crashing after re-installing WSUS

MMC console will crash after re-installing the WSUS and while running the WSUS post-install configuration.

The event viewer will show event ID 1000 with Faulting application name: MMC
Faulting application name: mmc.exe, version: 6.3.9600.17415.
Faulting module name: KERNELBASE.dll
If we use procmon when the MMC is crashing, the error points to the missing tools folder in Update Services under C:\Program Files\Update Services. 
After re-installing WSUS, if we check Update Services folder, we cannot find the Tools folder which has wsusutil.exe.

To fix the problem re-install the WSUS and make sure the tools folder is created. Otherwise copy the tools folder from other WSUS installation.

  1. Thanks for the tip!
    We had to install WSUS on another server and copy 3 folders over to the broken installation;
